For the default Mozilla build, this includes Composer and Mail Composition.
Embeddors willing to disable this feature should look at |nsHTMLEditor::SetIsImageResizingEnabled()|
Displays eight resizing handles plus an info box. Images are resized real-time.
Uses HTML attributes in pure HTML mode (mail composition for instance) and CSS properties when available.
Undoable and Redoable. Does not grind coffe and make a good expresso yet.
